lLetters .Patent No. 85,419, dated December 29, 1868.

HOISTIN'QAPPARATUS FUR BUILDERS.

The Schedule referred to in these Letters :Fatent `imei making parl: ofthe same.

To all whom it conce/rn:

Beit known that I, LEONARD ATwooD, ofthe city, county, and State of NewYork, have invented a new and useful Improvement in Hoisting-Apparatus;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making part of this specilication, in which- Figure 1 is a perspectiveview, and

Figure 2 is a vertical transverse section.

The. same letters are employed in both gures in the indication of thesame parts.

My improvement relates to platforms, used in connection withhoisting-apparatus, used by builders in the elevation of materialsemployed in the erection of houses; and

It consists in combining, with said platforms, a rack,

transversely arranged, and having a series of parallel rack-barscentrally attached' 12o/a transverse beam, and so arranged that a seriesof hods may be placed side by side, and attached or detachedindependently lfrom either end of the platform. In the annexed drawings-A is an ordinary hoisting-platform, such as is in com-` mon use inhoisting-apparatus, suspended by amepieces B B, attached on each sideofthe platform.

O -is the cross-piece, connecting the side-pieces B B at the top,through which is placed the eye-bolt O', into which the hoisting-rope orchain'is hooked.

The brace-rods D D are extended from the top-piece to the side-pieces,and the brace-rods E E are extended from the side-pieces to the cornersof the platform, as shown.

A cross-beam, F, is placed transversely across, between the side-piecesB B, and to it is bolted a series of 'parallel bars, G, equidistant fromone another, and of properv length, and atpr'oper distances apart, toreceive and support hodssilch as are in common use in carrying bricksand mortar to be used in building houses.

I am aware that frames have been heretb used in connection withplatforms 'to supportsuch hods, but they have been' so arranged thatonly a small number of hods could beused upon a platform,`as the frameswere placed so that the hods rested lengthwise with the transversediameter of the platform.

My improvement is distinguished from these by changing the arrangementof the racks, 4so that the hods, resting side by side, are placedlengthwise with lthe platform, and may he placed and displaced by aneither end, as may be most convenient.

What I claim as my invention, and desire to. secure by LettersPatent,ise p 4 lhe'parallel bars G G, attached to the Atransverse beam F, usedin combination with the platform and pose setforth.

In testimony whereof, I have signed my name to this =speciioation, inthe presence of two subscribing Witnesses. l
